Gitrog is known for being a strong commander, and a lot of Gitrog decks contain a few combos
If you have multiples of Dragoons Lance and Red Mages Rapier (by far the most powerful of the equipment cards in terms of pressuring life totals early) and copies of Suplex or Slash of Light to force through those attacks, you can go all-in with finishers like Unexpected Request and Zidane, Tantalus Thief to steal games before the opponent gets going
The drawback is that the controller gets a basic land in return, but in a meta where turn-three kills are a reality, thats a trade you should be happy to make
